Here's a roundabout related answer, if this helps.
I did a small boat charter, with another family, although it was mainly for the ride and to see the island from offshore. Part of the trip included fishing.
I had never fished before, because I've had a phobia about fish. Anyway, I had a go at fishing that day, and was quite pleased with myself. They showed me how to tie a thingy onto the end of a line, get the hooks on, cut up bait, stick it on the hooks, drop the 'plumb' to the bottom, keep it there until it gets wedged, then pull it up and break the line. Great. So I can do that now.
Meanwhile, 3 got seasick, 2 got sunburnt, pm was really overcast, 1 kept moaning that she was hungry, the skipper burnt a hole in the coffee pot, we saw some dolphins go by, a fish tried to jump out of the bucket and gave the kids a fright and I found out that some fish have massive tongues when caught.
